Sourcing Metal ducting in Los Angeles area

[jussi]

Hoping to upgrade my ducting this year and go metal.   Nordfab is way too expensive for me.  I've seen posts of people getting the spiral stuff locally for significantly cheaper than Nordfab. Unfortunately the places are not local to me
.  So I'm wondering if anyone knows of a local place in Los Angeles or OC area for 6" (maybe even 8") metal ducting.

Come to IL. Ill sell you a haulmark trailer full of 6" and 8". I am going all nordfab instead.

I generally go to an HVAC supplier and can get reasonably priced ducting there. I did that to handle some additional run on my Oneida system - I happen to be on the other end of LA (Thousand Oaks), so don’t have a supplier for you
